I think it would be unfair of them to ask you technical questions beyond PPL level since I'm guessing you have little or no flying experience.
I would suggest you look into the MPL license they offer. I stand to be corrected but don't think many if any (yet) other airlines recognize it.
Which means your options are somewhat limited should things go sour and you need to seek employment else where.
Still good luck and go for it, just check things out throughly
